What becomes of a YY genotype?
In mice the YY genotype is lethal during embryonic development. This means that the mating of heterozygous individuals will produce a ratio of 2:1 Yy to yy offspring.A 'YY' genotype is homozygous dominant for that particular trait. If it is Yy, it will be heterozygous.
What trait masksthe othor form of a trait?

What is the probability that a pregnancy will abort if the mother and father both carry a lethal recessive allele?

What is the pattern of sex linked inheritance?
In humans sex linked traits are passed on the X chromosome. (For the purpose of this discussion the trait being passed is recessive.) This means that a male parent cannot pass the characteristic on to his male offspring, but he can pass the trait on to his female offspring. The female parent can pass the trait on to any of her offspring. Both parents must carry the allele for the sex-linked trait (and pass it on) in order for a female child to have the characteristic. Male children that get the trait from their mother will have the trait no matter what the genetics of the father. If the female parent is heterozygous for the trait 50% of her male children will have the characteristic no matter the father's genetics for that trait. Assuming that the characteristic is not lethal and both parents are "carriers" (keep in mind that the father displays the trait and a heterozygous mother will not)... 50% of the sons will have the trait, 50% of the sons will not have the trait, 50% of the daughters will be homozygous for the trait and 50% will by heterozygous "carriers".
What is dominant lethal allele?
Dominant lethal is a genetic trait. If the genome of an individual has the trait, it is expressed and makes it impossible for the individual to have descendants. Its effects cause foetal or embryonic death.
What becomes of a YY genotype?
In mice the YY genotype is lethal during embryonic development. This means that the mating of heterozygous individuals will produce a ratio of 2:1 Yy to yy offspring.A 'YY' genotype is homozygous dominant for that particular trait. If it is Yy, it will be heterozygous.
